SYNTHESIS OF PERFLUORO-OXA-ALKYLATED COMPOUNDS BY THE USE OF PERFLUORO-OXA-ALKANOYL PEROXIDES AND THEIR APPLICATIONS

A series of perfluoro-oxa-alkanoyl peroxides [(R(F)CO2)2; R(F) = C3F7O{CF(CF3)CF2O}mCF(CF3); m = 0, 1, 2] has been prepared by the reactions of the corresponding acyl fluorides and hydrogen peroxide under alkaline conditions. It has been demonstrated that perfluoro-oxa-alkanoyl peroxides are convenient tools for the introduction of perfluoro-oxa-alkyl groups into organic molecules with carbon-carbon bond formation. Such perfluoro-oxa-alkylated compounds possess unique properties such as extremely low surface tensions and new biological activities not demonstrated by the corresponding perfluoroalkylated materials.
